these arms and oE the lugs '20 and 21 of the levers 15 and i6. The,

the piston rod with 2d with the ears of the levers, as

pivotal connection Aof 12, permits the movement 'l will be described.

With the parts constructed as llbove described and in the position shown in Fig. l, when sudden pressure is exerted on the bottom l of the vehicle, the spring I will be compressed, causing the vehicle bottom to lower on the free ends of the lever arms l5 and 16, thereby csusing said levers to move outwardly in thehangers 2 and fi, thereby changing the point of contact ol? said levers with said hangers and shortening the levers and causing their ulcrnmed ends to move inwardly whereby the shoes i8 and 19 engege and compress the cushioning member 10; simultaneously the pistons 26 and 2T are forced toward the open ends of the cylinders 22 and 23 during which movement the spring pressed valves 28 are opened and tile air in the cylinders forced therethrough bf ind the pistons, When the rebound ce pistons move rearwardly tova o .s ends of the cylinders, the air f ders behind seid pistons .i y v L through the valve controlled fr in, openings- 25 whereby the shock is si "mi From the foregoing de` seen that the sudden shocks i ifi to the vehicle and the wheels thcrer bsorbed by the pneumatic checlr. mechanism above described, `which acts in conjunction wi the other supporting springr preventing,p springs from acting too suddenly und a relieving the strains thrown on the springs Whenithe Wheels drop suddenly into n deep `rut or Strike a serious obstruction.

' l claim as my invention:

l. AA combined cushioning spring and. shock absorber comprising en axle engaging element, o pneumatic cushioningI spring; mounted on said element, levers .iulcrunied it will be at one end on said axle engaging element and having shoes for engagement with said cushinning element. shock absorbing cylinders, pistons carried by said levers and slidzibly mounted in said cylinders, and means vfor slidably supporting the i'ree .ends of said levers.

2. A combined cushioning spring and shook absorber comprising an axle engaging; element, s pneumatic cushion mounted on 'said element, levers fulcrumed et one ond on said sxleengaging element und having their opposite ends curved upwardly and ontmoonen vrai-diy, ineens selected to'be secured to s. vehicle body 'for sli` ibly supporting the r ends seid levers, shoclr sbsorbing cylinders mounted on seid aisle engaging element, depending arms on said levers, pistons slidable in said cylinders and piston rods connected with seid pistons and with the free endsoi seid orins. y

3. A combined. cushion spring end shook absorber comprising n substantially annuler hub adapted to be mounted on 'e vehicle axle sind having n peripheral groove, s substantially snnulmpneurnstic cushion seated in said groove, s spring pressed shoe for engagement with said snnuisr cushion to hold it seated in said groove and to prevent bulging thereof, levers fulcruined et one end on said hub and provided *with shoes positioned to engage seid cushion nt opposite sides thereof, hangers adopted for attachment to n vehicle body and to receive the 'free ends of said levers whereby seid lever ends are slidably mounted relatively to seid hangers, shoclc absorbing oylind rs carried by said hub und having slidnble therein, scid pistons being provided with outwardly opening spring` pressed valves, seid cylinders luiving 'vent openings at their outer or rear ends, sud inesns for connecting,` seid pistons with said levers.

'l iorbin Gill cushion spring end shocir ising snbstsntislly annuler unil red on n vehicle side ipherei t'ro-ove, n substanieiuemtic cushion sented in y i f' pressed shoe for en ivi( id annular cushion to hold in esili. groove rind to prevent bulg-- ing the iol?, level-s J{"iilcrunied et one end on said huh :ind provided with shoes positioned to said cushion at opposite sides tiioreoh hangers adapted 'for attachment to iiiele body and to receive the free endsl levers, wluereby said lever ends are nel :mii lowing' ai ially finnois Hzllli short; rliing cylinders carried by seid hub and inning pistons slideble therein, seid pistons being provided with. oiitwnrdly openinnv ;-=piing pressed valves, snidcylinderslmving vent openings at their outer ends, ineens for connecting said pistons with said levers, said cylinders being pivotslly supported at their opposite ends.

il. ronihined cushioning Spring and shock absorber comprising an zlXle engaging hub 1formed in hingedly connected sections mul haring periphernl groove therein, an arcuate cushioning member sented in seid groove, n'ienns for holding seid cushioning member in seidffroove, levers having biiurcaied inner ends iulrrumed onsoid heb, the arms oi' said levers spanning said hub and cushioning member, cushion engaging shoes pivotally mounted in the erotehes of? seid levers, arms depending from seid levers,

ibiy mounted relatively to said hangers,

:ist

maaien 6. The combinatiin with a vehicle body having longitudina ly spaced hangers secured to the bottom thereof, a hub engaging the axle of said vehicle and comprising arcuate sections hingedly connected at one end and provided with outwardly extending laterally projecting apertured lugs at their free nds, a bolt/engaging said lugs for clamping said hub sections to said axle, said hub having a peripheral groove therein, a substantially annular cushioning member seated in said groove, a coil spring mounted on one of the hangers of saidvehicle body and provided at'its free end with a cushion engaging shoe arranged midway the ends of said cushioning member, levers .iii the form of" ogec curves having their inner ends bifurcated and fulcrumed on the pintlc Which connects the sections of said hub, the arms of said bifurcated ends spanning said hubs and the cushioning member mounted thereon, cushion engaging shoes lpivotally mounted on said levers in the crotches thereof, the free ends of said levers being slidably engaged with two of `the hangers'on said veh icle body and extending in opposite directions, rigid arms depending from said levers,

shock absorbing cylinders closed at one end and open at the other, means for'pivotally connecting the open ends of said cylinders with said hub sections, valved pistons slidably mounted in said cylinders,`said cylinders having valve controlled vent openings near their closed outer ends, and piston rods rigidly connected with said pistons and slidably mountedvin said hcylinders, the outer ends of said piston rods being pivotally connected vwith the free ends of the lever carried arms.
